147088: Ruling on prostrating for forgetting Qunoot or forgetting to recite out loud

Do I have to do the prostration of forgetfulness when I forget to say the du’aa’ of Witr? Should I do the prostration of forgetfulness if I do not recite out loud at times when the recitation should be out loud, because I forgot?.

Praise be to Allaah.

If a person omits the Qunoot of Witr because of
forgetfulness or he does not recite out loud in a prayer where the
recitation should done out loud, out of forgetfulness, he does not have to
do the prostration of forgetfulness, but if he does prostrate there is
nothing wrong with that. Doing the prostration of forgetfulness for
omitting a Sunnah of prayer is permissible, but it is not obligatory. End
